Whey, Vegan, Collagen, and BCAA protein powders explained

Whey, Vegan, Collagen, and BCAA protein powders explained
June 19, 2020 Marisa Michael

Protein powders can be confusing! There are so many on the market, and so many messages we hear about them. Which one is right for you? Or do you need a different one in different situations? Whey, collagen, vegan powders, and BCAAs all have specific uses. Read on to figure it all out!

Why do you need a protein powder?

Well, you may not need one at all! Food first is a good philosophy. But sometimes a protein powder can be useful. If you are really busy and can’t find the time to eat a full meal, protein shakes are a good option as long as you can pair it with some food. Some people like the convenience of protein powders. And they can also be useful to help you meet your overall protein needs, especially if they are high (such as during a strength training phase, weight loss phase when trying to preserve lean mass, or you have an injury that requires more protein to heal).

What are some drawbacks of protein powders?

Many are contaminated with fillers, heavy metals, banned substances, and other undesirable products. Be sure to check for the NSF for Sport or Informed Choice logo on the label. This means it has been third-party tested for purity. Many vegan powders have more contaminants than whey. 

Another drawback is that you are not eating a whole food. When you eat food, it contains vitamins, minerals, fiber, phytonutrients, antioxidants, and other healthful compounds (depending on the food, of course!). When you eat a highly processed powder like a vegan protein powder, you are missing out on all the wonderful things the more whole plant could have provided you.

Whey is the gold standard for protein powder

If you’re looking for muscle growth, strength, rebuilding, repair, and recovery, whey is the way to go. It is a complete protein source, meaning it has all the amino acids. This is important, as muscles need a full complement of amino acids in order to grow and repair. It also is high in leucine, which is a particularly useful amino acid involved with signaling muscle protein synthesis. Numerous studies comparing whey to plant proteins show that whey is superior for muscles.

For best results, consume quality whole food protein (egg, cottage cheese, milk, salmon, chicken, or beef) within about 2 hours after working out at around 20-30 grams for your meal. If you need to use a protein powder, use whey (2 scoops is usually around 20 grams for most brands).

You’ll also need adequate calories for muscle growth–so be sure to eat enough!

Collagen is used for tendon and ligament strength and repair

Collagen is another useful protein powder. It serves a totally different purpose than whey. It has been shown to strengthen tendons and ligaments when taken about 30 minutes BEFORE a workout, along with some vitamin C. The collagen and vitamin C work together to strengthen the tendon and ligament when they are under an exercise load, or under stress when you work out. This can also be used if you have a soft tissue injury.

To use, take collagen before your workout or physical therapy session–about 20 grams combined with 50 mg vitamin C. Read more on collagen in our other post.

Collagen is very different from whey and has a different application. It also doesn’t have a good source of all amino acids, including leucine, so bear that in mind. If you’re looking for muscle building and support, use whey (or food!). If you want tendon/ligament support, use collagen. Don’t think that by taking collagen you are necessarily going to support muscles. Although it’s not useless for this, it just different.

Vegan protein powders

Honestly the only reason I can think of to use a vegan protein powder is if you’re vegan. For any kind of muscle or soft tissue strengthening/building, whey is better than soy, hemp, pea, rice, or a blend. “Plant-based” is all the rage right now, and if you’re aiming for a plant based diet that’s great. But that doesn’t mean you need to use an inferior protein powder. If you’re not vegan, use whey. You can still be plant-based while using whey!

Vegan powders have the drawback of more risk for contamination, an incomplete amino acid profile (except soy and some blends), and a low source of leucine. They sometimes also have added fiber and carbohydrate, which is silly if you’re buying a protein powder for the protein.

If you want to use vegan protein powder as an on-the-go meal replacement, go for it. But if you’re using it thinking that it will help with muscle repair and building, trade it out for whey.

What are BCAAs used for?

BCAAs are used to put money in the pockets of supplement companies.

Ok, I kid, but only sort of. They are not actually good for much. While it is true that BCAAs (branched-chain amino acids) are important for muscle building and repair (leucine is a BCAA), it’s not generally true that you need to supplement with them separately. 

Here’s why:

BCAAs are readily found in foods people normally eat, and in the dose you would need to build and repair muscle. Things like chicken, beef, salmon, eggs, and milk all are rich sources.

BCAAs are also already in whey, so if you’re using a protein powder, use whey, not BCAAs (and definitely not both).

BCAAs are not a complete protein. BCAAs, and leucine in particular, are needed for muscle protein synthesis. But that’s not the whole story. More research is showing that muscles like a full amino acid profile on board. If you are eating just BCAAs without other amino acids, you’re missing out! (Although if you eat a balanced diet, you’d be fine–but then why do you need BCAAs?).

The only reason someone may need BCAAs is if you are vegan and it’s difficult to get adequate leucine in your diet. Other than that, ditch the (gross) and expensive BCAAs and opt for a clean whey powder that is third-party tested.
